drm/amdgpu: Add sysfs interface for gc reset mask
Add two sysfs interfaces for gfx and compute:
gfx_reset_mask
compute_reset_mask
These interfaces are read-only and show the resets supported by the IP.
For example, full adapter reset (mode1/mode2/BACO/etc),
soft reset, queue reset, and pipe reset.
V2: the sysfs node returns a text string instead of some flags (Christian)
v3: add a generic helper which takes the ring as parameter
and print the strings in the order they are applied (Christian)
check amdgpu_gpu_recovery before creating sysfs file itself,
and initialize supported_reset_types in IP version files (Lijo)
v4: Fixing uninitialized variables (Tim)
